Hi. I'm online and happy to answer your question today.
There are a number of reasons why one eye can look smaller then the other. The best way to diagnose what is causing this is with a complete eye exam by an ophthalmologist. In addition to doing the usual exam she will examine your eyes and orbits with a special instrument called a hertel exophthalmometer.
This instrument measures how much each eyeball protrudes from the orbital rim. With this information and, if needed, other testing, the cause of your issue can be determined.
As you have already discovered, a GP doesn't have the training nor the equipment to adequately address your concerns.
Does this make sense to you?
Thank you, XXXXX XXXXX that there could be a number of reasons for this, I wonder, could you name a few.
The most common would be either a mild droopy eye lid or a retracted eye lid. These eyelid issues can be caused by many things, such a weakness of the muscles of an eyelid, or overactive lid muscles. Also, an orbital mass can make one eye stick out farther then the other, but this would not vary from time to time like yours is. The list of possible causes is very long and branching however a good exam will be able to narrow things down.
Does this answer your question or were you looking for a laundry list of disease processes, ranging from the benign to the awful? I don't think a list like is very useful as they would just be guesses without data from an exam :)
Are you still there?
I guess you have stepped away from your computer....
